func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]?{
        shareMicroId = (idArray?[indexPath.row] as? String)!

        let share = UITableViewRowAction(style: .normal, title: "分享"){action, index in
            //分享处理
        }

        let delete = UITableViewRowAction(style: .normal, title: "删除"){action, index in
            //删除处理
        }
        delete.backgroundColor = UIColor.red

        return [delete, share]
   }
